About the Airtac ACE Compact Cylinder ACE32X120S
This AirTAC ACE32X120S is a double acting compact cylinder with a 32 mm bore and 120 mm stroke, delivering 402.1 N of push force at 0.5 MPa. Its ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a longer cylinder will not. The hard-anodized aluminium body and S45C hard-chrome rod resist wear in continuous cycling.
With the optional -S magnet fitted, this model works with CMSE or DMSE reed and solid-state switches for reliable position sensing. For real work, plan on about 241 N of usable force at 0.5 MPa, which lifts roughly 24.6 kg vertically with a 2:1 safety margin. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the 1/8" port suits standard air line fittings.

Where the Airtac ACE Compact Cylinder ACE32X120S Is Used
Fixture Clamping on CNC
Use this 32 mm bore cylinder to clamp small workpieces in a CNC vise or fixture. Its 402.1 N push at 0.5 MPa holds parts securely, and the short body fits under the spindle guard without protruding.
Stop Gate on Packaging Line
Mount this cylinder on a conveyor to operate a stop gate for cartons. The 120 mm stroke moves the gate fully out of the path, and the fixed TPU bumper prevents shock to the product at line speeds up to 500 mm/s.
Press for Small Assembly
In a benchtop press for inserting bearings or bushings, this cylinder provides 402.1 N of force. The compact body saves space on the workbench, and the optional -S magnet lets you confirm the press stroke with a sensor.
Is the Airtac ACE Compact Cylinder ACE32X120S the Right Cylinder?
Choose this 32 mm bore ACE32X120S when you need a compact actuator with moderate force. If your application requires less push, the 25 mm bore offers 245.4 N at 0.5 MPa, while stepping up to a 40 mm bore gives 628.3 N for heavier loads. The 120 mm stroke is within the 200 mm standard maximum for this bore, so no special order is needed. Since this unit carries the -S magnet, you can mount CMSE or DMSE switches directly to track piston position. Mounting options like FA/FB flanges or LB foot brackets bolt straight to the ISO 21287 face.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACE Compact Cylinder ACE32X120S FAQ
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. These figures are for double-acting operation.
The ACE32X120S has a short body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder. This lets you install it in tight spaces like machine guards or gantries. The fixed TPU bumper absorbs end-of-stroke energy, and the optional -S magnet allows CMSE or DMSE sensors for position feedback.
